With 50,000 cycling injuries annually, and only a portion of which involve head injuries, that would be something less than three thousand that it might help, not three million.
Although the 6% number has little credibility - not exactly rigorous science. Credible estimates range from around 40% to 70% for traumatic brain injury.
